description/ordering information
The ’BCT2244 devices are designed specifically
to improve both the performance and density of
3-state memory address drivers, clock drivers,
and bus-oriented receivers and transmitters.
Together with the ’BCT2240 devices and
SN74BCT2241, these devices provide the choice
of selected combinations of inverting and
noninverting outputs, symmetrical active-low
output-enable (OE) inputs, and complementary
OE and OE inputs. These devices feature high
fan-out and improved fan-in.
To ensure the high-impedance state during power
up or power down, OE should be tied to V
CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
The outputs, which are designed to source or sink
up to 12 mA, include 33-Ω series resistors to
reduce overshoot and undershoot.
